LOOKING-LEVER FOR CAR-COUPLINGS.

SPECIPICATON forming part of Letters Patent No. 384,779. dated dune 19, A1888.

Application led January 31, 188B. Serial No. 262,530.

To all whom it may concern:

Be it known that I, FRANCIS W. PARsoNs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful .Improvements in LockingLevers for Car-Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to improvements in lockinglevers for car-couplings of that class known as the Ames coupling, and among the objects in view is to reduce the amount of steel stock consumed in the formation of the lever, thus effecting a saving in the cost, and this without weakening or otherwise affecting said lever.

Other objects and advantages of the invenltion will hereinafter appear, and the novel features thereof be particularly pointed out in the claims.

Referring tothe drawings, Figure l represents a locking-lever constructed in accordance with my invention. Fig. 2 is a longitudinal section ofthe same, and Fig. 3 a plan.

Like letters indicate like parts in all the gures ofthe drawings.

A represents the lockinglever, which is of the usual construction,and is formed with the laterally-projecting trunnions A', which are journaled in the head, the forward-projecting coupling portion A3, and the rear weighted portion,A". This locking-lever it is the practice to form of cast'steel, whereby a great amount of the stock is necessarily consumed.

VBy my invention I propose to reduce the rear end up to a point near the coupling end A3, thus leaving an outer surface of cast-steel, which will give the lever the required strength.

.cast steel having an internal chamber provided (No model.)

site weight necessary for the automatic action 5o y y f After the lever has been thus formed,l molten in coupling.

For the purpose of locking the filling B within its chamber A5, the chamber is contracted, as at A6, at its opening where the metal enters, which contraction forms a shoul- 5 5 der, thus obviating the liability of the lling slipping out, which might be caused by the expansion of the metals as cliected bythe atmosphere. In this regard, however, I do not limit my invention. r

Having describednmyinvention, 1s-

1. A locking-lever for car couplers having an internal chamber provided with a iilling, substantially as specified.

2. A lockinglever for car-couplers provided with an internal chamber having a contracted neck and a filling for said chamber, substantially as specified.

3. A locking-lever for car-couplers having an internal chamber formed with internal lockingshoulders and provided with a filling, substantially as specied.

4. A locking-lever for car-couplers formed of 5c whatIclaim with a lling of cast-iron, substantially as specified.

5. A locking-lever, A, having trunnions A and coupling end A3,and internally chambered, as at A5, said chamber having contracted neck A6 and provided with a filling, B, substan tially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

FRANCIS W. PARSONS.
